The production of slag is an integral function of current steelmaking practices. MultiServ's extensive experience in the efficient removal, handling and processing of slag allows steelmakers to focus on their core metal production processes. We select the most appropriate methods and equipment to meet the client's requirements through the application of our global best practice.

After controlled cooling slag is dug and transported from the pits for de-metalisation and processing in Serbia. Recovered metallics are returned to the client for recycling and can be upgraded to high Fe content for increased value in use.

MultiServ operates over 150 specialised carriers transporting molten slag in pots ranging from 6m³ to 35m³. MultiServ ensures all slag handling operations are safe and efficient. All hot work equipment owned and operated by MultiServ is fitted with a liquid-based fire suppression system which helps to protect the operator from heat and fumes if a fire occurs.

Maximising the working life of slag pots is becoming increasingly important. Slag pots are cycled to optimise thermal loading. Cold graded slag is added and pots are sprayed with special agents to help prevent stickers and reduce the need for knocking.

Liquid slag is tipped into purpose designed slag pits and cooled under carefully controlled conditions. Slag is then processed to recover the metallic content for re-use by the client. De-metallised slag is weathered, crushed and screened into various sized products for sale by MultiServ or the client.

Developments in slag handling include rapid cooling, granulation and atomisation of slag, allowing the production of higher value products, and the stabilisation of falling stainless steel slags to reduce environmental issues.
